Center Enamel Advances Municipal Wastewater Treatment with Glass-Fused-to-Steel Tanks in Henan Project
Center Enamel is proud to announce its pivotal role in the successful implementation of the Henan Municipal Wastewater Treatment Project, completed in 2022. This landmark environmental infrastructure initiative underscores Center Enamel's ongoing commitment to delivering high-quality, sustainable, and reliable storage solutions engineered to meet the demanding requirements of large-scale municipal wastewater treatment facilities.
Project Overview and Technical Specifications
Located in Henan, China, the project required robust, high-capacity storage solutions capable of efficiently managing complex municipal wastewater streams. Center Enamel supplied a comprehensive multi-unit array of meticulously engineered Glass-Fused-to-Steel (GFS) tanks, customized to fit the rigorous hydraulic and operational demands of the treatment plant:
● Project Location: Henan, China
● Application Area: Municipal Wastewater Treatment
● Completion Year: 2022
● Operation Status: Fully operational
● Tank Configurations & Capacities:
○ 23.69m x 7.21m (H), 1 set (3,182m3)
○ 22.17m x 7.2m (H), 1 set (2,778m3)
○ 21.02m x 7.2m (H), 4 sets (2,505m3 each; total 10,020m3)
○ 15.29m x 6.0m (H), 4 sets (1,105m3 each; total 4,420m3)
○ 9.94m x 6.0m (H), 1 set (465m3)
● Total Tank Volume: 20,865m3
● Material Technology: Glass-Fused-to-Steel (GFS), renowned for superior corrosion resistance, structural durability, and long-term reliability in aggressive municipal wastewater environments.
Advanced Engineering for Municipal Wastewater Infrastructure
Municipal wastewater treatment plants handle large volumes of diverse effluents containing organic loads, suspended solids, and chemical cleaning agents that rapidly degrade traditional concrete or welded steel basins. Center Enamel's GFS technology provides distinct advantages:
● Permanent Glass-Steel Fusion: Fusing molten porcelain enamel glass to high-strength structural steel plates at extreme temperatures (820C to 930C) creates an impermeable molecular barrier that resists corrosion, abrasion, and chemical attack.
● Rigorous Quality Control: Every modular panel undergoes strict high-voltage holiday testing (1500V) before dispatch to ensure zero pinhole defects and absolute structural integrity.
● Rapid Modular Erection: Prefabricated bolted modules enable fast, safe on-site assembly with minimal heavy equipment requirements, reducing construction timelines for large-scale municipal projects.
Comparative Matrix: Municipal Wastewater Storage Technologies
Evaluation Parameter | Center Enamel Glass-Fused-to-Steel (GFS) Tanks | Cast-in-Place Concrete Basins | Traditional Welded Carbon Steel Tanks |
Corrosion & Chemical Resistance | Permanent high-temperature glass-steel fusion completely resists municipal wastewater chemicals and sludge | Prone to concrete carbonation, acid etching, and structural micro-cracking | High susceptibility to interior oxidation, pitting, and protective paint breakdown |
Installation Speed & Rigging | Rapid modular bolted construction completed efficiently with minimal footprint and labor | Extremely slow civil construction requiring formwork, pouring, and long curing cycles | Slow field construction requiring complex manual welding and site protective coatings |
Maintenance Requirements | Minimal; smooth non-porous glass surface prevents sludge buildup and requires no recoating | Moderate to high; requires crack sealing, chemical waterproofing, and structural repairs | High; requires recurring abrasive blasting and protective interior repainting |
